The DEWALT® Fab-Lok® Fastener with Carbon Steel Screw is engineered for high-performance fastening in a wide range of construction and fabrication applications. Combining the strength of a carbon steel screw with the versatility of a controlled expansion body, the Fab-Lok® system delivers unmatched holding power—especially in soft or thin materials.
Vibration, either from inside or outside a building, can make ordinary fasteners loosen and back out. Fab-Lok® fasteners combine a screw and a slotted aluminum sleeve to provide resistance to loosening in high-stress and high-vibration environments.
